.To all whom it mag concern.-

Be it known that I, JULIUS BREN'ZINGER, a citizen of Germany, and a resident of New York city, county and 8tate of New York, have invented certain new and useful Improvements in Can-Heading Machines, of which the following is a specification.

This invention relates to an improved ma chine for securing can-heads to flanged canbodies by a double'lap-joint.

The machine produces a large output, forms a perfect air-tight joint, is readily adjustable, and does not require skilled attendance.

In the accompanying drawings, Figure 1 is a front elevation of the machine; Fig. 2, a side elevation thereof; Fig. 3, a vertical section on line 3 3, Fig. 2; Fig. 4, a horizontal section on line 4 4, Fig. 1; Fig. 5, an enlarged section on line 5 5, Fig. 2; Fig. 6, a detail of part of roller 1; Fig. '7, an enlarged section on line 7 7, Fig. 2'; and Fig. 8, a detail of part of roller m.

The letter 0, represents the frame of the machine, and b is the rotatable platform on which the can-body to be headed is supported. Above this platform is arranged a chuck 0, adapted to bear upon the can-head and to rapidly rotate body and head simultaneously while they are subjected to the action of the seaming rollers.

Rotary motion is imparted to shaft 0' of "chuck'c from pulley d of power-shaft d by belt 6, running over idlers e and over pulley c of shaft 0'. The power-shaft (1 also drives by belt f, running overidler f, a pulley g loose on shaft g. This shaft is provided with a worm 9 that engages a worm-wheel 71., fast on shaft h, and is adapted to intermittently drive said shaft in manner hereinafter specified. The shaft It carries two cams i j, that are adapted to project the seaming-rollers toward the work in the following manner: The first cam 't', Fig. 5, is engaged by a roller 2" of a lever 13, to the forward end of which is pivoted'an upwardly-projecting wedge i This wedge when rising bears against the roller 70' of a slide 10, in the forked forward end of which the first seaming-roller Z is pivoted.

' Thus the roller Z engages the flanges A B of the can-body A and cover B, and its profile is so formed that it will bend them into a double lap-seam, Fig. 6. When the earn 1' allows lever i and wedge 2' to drop, the slide it willbe drawn back by spring k In order to permit a delicate adjustment of the roller Z with relation to the work, I form back of wedge i an adjustable abutment, consisting of a pivoted bar 1 carrying antifriction-roller i and adapted to be fixed at different inclinations by set-screws t. The cam j, Fig. 7, actuates the second seaming-roller m in a similar manner by roller j, lever j wedge j roller n, and slide 72., in the forward end of which the roller m is pivoted. The profile'of this roller is such that it will flatten or compress the seamdoubled by roller 1, Fig. 8, so as to form a fiat air-tight joint. The abutment of wedge is formed by the pivoted barf, carrying roller 7' and bearing against an elastic cushion or spring f, the bar 7' being adjustable by bolt and nut 7' This elastic abutment permits the roller m to hug the contour of the can-body at the side seam and closely compress the lap-joint over such seam, so that imperfections in the joint and jamming are avoided.

The cam i is keyed to the shaft it, while the cam j is adj ustably attached to cam 't' by means of set-screws 7' engaging elongated slots i of can; 2'. Thus the relative position of the cams can be readily adjusted to adjust the movement of the seaming-rollers in their relation to one another.

In order to permit the slides to be set to can-bodies of different diameters, the shaft h as well as the abutments and slides are supported by a carriage a, movable upon bracket or of frame a and held in position by setscrew a Fig. 3. The support I) of can A is provided with a spindle I), stepped into the upper end of a sliding bar 0, embraced by sleeve (1 of frame a. The bar 0 is surrounded by a sliding collar 0, Fig. 5, that constitutes the support fora pair of springs 0 over which is arranged a collar 0 adapted to be adj ustably clamped to bar 0 by set-screw 0 After the can has been placed upon platform I) the latter is raised, so that the can-head is engaging with itseccentric end 12 a pair of I shafts gh. The operation is as follows: The flanged.

desired, be connected by chain 19 to a treadle p When the lever 19 is swung down,- the eccentric 10 by bearing against rollers 0 will lift rod 0 through collar 0, springs 0 very large output. 7

What I claim is- I I 1'." ,In a can-heading machine, a seamingroller, a slide carrying the same, a cam, and

and collar 0 and will thus press the canhead against the chuck c. The springs 0 will form a yielding bed to compensate for slight differences'in the height of the can-bodies. The connection between the can-support and the worm-shaft g is such that when the cansupport is raised the shaft will be once r0- .tated to rotate cam-shaft hand project the, seaming-rollers Z m successively against the ,work. After the cam-shaft has made a complete rotation and the slides have been drawn back by the springs 10 n the worm-shaft is arrested to arrest the seaming rollers in their rearmost position, and the can support is lowered ready to receive a fresh canbody. 7 The constructionfor effecting these results is as follows: The lever 19 is provided with an arm 10 connected by rod q to lever q, carrying roller q ,-that is engaged by a third cam 4, fast on shaft h. To lever q is secured one end of a springs, containing a core-rod s and secured at its other end to a lever t, actuating clutch t, by means of which the loose pulley 9 can be coupled to its shaft g. When the lever p is depressed to raise the can-support, the lever q will be so vibrated that the draw on spring 8 will shift lever 13 to couple pulley g to shaft g, and thus advance the rollers l msuccessively against the work. Meanwhile the rollerq will engage cam r, and when the shaft it has made a complete turn the roller will be forced into the receding section of the cam-surface by a spring t", secured to lever 19. This will cause lever q tobe so vibrated thatlthe core -rod swill push against theclu'tch-lever t to shift clutch't', release pulley g from shaft g, and arrest can-body A, with the head B superposed, is placed upon the platform 6, and the latteris raised so that the head is pressed firmly against clutch c, by means of which head,

body, and platform are rapidly rotated. The raising of platform I) has coupled the shaft 9 to the power, and thus the cams i j are rotated 130 raise the wedges 01 j and advance therollers'Z m successively against the work, so as .to first fold and then compress the seam.

After the shaft It has made "a complete turn,

the engagementof concavepart of cam a" with roller (1 will cause the clutch t to be shifted fso as'to uncouple'pulley g and arrest shafts g h. At the same time the lever p will be so vibrated as to lower its end 10 and permit the platform-support to drop and disengage the 'ti'ally as specified.
